The BF2 Helmsman is a folding dive knife with a 3.5-inch Bohler N690 stainless blade finished in stonewash, featuring a partially serrated drop point profile. The linerlock secures the blade during use, while a thumb stud enables one-handed opening. The gray anodized aluminum handle closes to 4.75 inches and includes a marlin spike for prying and utility tasks, a lanyard hole for attachment, and a pocket clip for carry. The combination of serrated and plain edge, stainless steel construction, and integrated tools makes this design practical for both underwater work and general outdoor use.
